| my.bisec {ebGenotyping} | R Documentation |
This function is to apply bisection method to find the root of a function f.
my.bisec(f, int.l, int.u, eps = 1e-06)
f |
the function for which the root is sought. |
int.l |
a vector containing the lower bound of the interval to be searched for the root. The length of the vector is the same as that of the input of function f. |
int.u |
a vector containing the upper bound of the interval to be searched for the root. The length of the vector is the same as that of the input of function f. |
eps |
a single value: a threshold to control the convergence criterion. The default is 1e-06. |
Both int.l and int.u must be specified: the upper bound must be strictly larger than the lower bound.
The function f must be well defined without invalid output(NA, nan, Inf, etc).
The length of the input of function f, the output of function f, int.l and int.u must be the same.
a vector containing the root of the function. If there is no root in the interval (int.l, int.u), lower bound of the interval will be returned.
